Abstract
The utility model provides a kind of bell furnace hydrogen gas recovering device, comprises hydrogen recovery channel, and described hydrogen recovery channel inlet end connects bell furnace outlet side, and hydrogen recovery channel outlet side connects bell furnace inlet end; It is characterized in that: according to hydrogen flow direction, cooler, hydrogen purifier, hydrogen memory and pressuring machine are installed in described hydrogen recovery channel successively; Be connected with hydrogen diffuse channel between described hydrogen recovery channel inlet end and cooler, described hydrogen diffuse channel is provided with the first magnetic valve, between described hydrogen diffuse channel and cooler, the second magnetic valve is installed; Described hydrogen memory is provided with the first Pressure gauge, and be provided with control valve between described hydrogen memory and pressuring machine, bell furnace inlet end is provided with the second Pressure gauge.This device can recycle the hydrogen of bell furnace, the hydrogen gas pressure stabilization provided, and structure is simple, economical and practical.
Description
technical field
The utility model relates to the recycle device of hydrogen, is specifically related to a kind of recovery and recycling device of bell furnace hydrogen.
Background technology
Tradition bell furnace nitrogen hydrogen mixeding gas is as protective medium, and it is good that hydrogen has thermal conductivity relative to nitrogen, and the advantages such as density is little, dynamic viscosity is little, reproducibility is strong, instead of nitrogen hydrogen mixeding gas gradually as protective gas.From bell furnace discharge hydrogen purity more than 98%, directly as fuel gas, if through suitable purifying and process, can enter in bell furnace and recycle.It is intermittent for producing due to each table of bell furnace, and the flow of hydrogen is very unstable, and normal multiple control valve and the pressure transmitter of needing is monitored and regulate the Hydrogen Vapor Pressure in recovery channel.
Utility model content
The utility model provides the recycling device of the hydrogen in a kind of bell furnace, and this apparatus structure is simple, automaticity is high, the hydrogen gas pressure stabilization that provides.
The technical solution of the utility model is: a kind of bell furnace hydrogen gas recovering device, comprises hydrogen recovery channel, and described hydrogen recovery channel inlet end connects bell furnace outlet side, and hydrogen recovery channel outlet side connects bell furnace inlet end; It is characterized in that: according to hydrogen flow direction, cooler, hydrogen purifier, hydrogen memory and pressuring machine are installed in described hydrogen recovery channel successively; Be connected with hydrogen diffuse channel between described hydrogen recovery channel inlet end and cooler, described hydrogen diffuse channel is provided with the first magnetic valve, between described hydrogen diffuse channel and cooler, the second magnetic valve is installed; Described hydrogen memory is provided with the first Pressure gauge, and be provided with control valve between described hydrogen memory and pressuring machine, bell furnace inlet end is provided with the second Pressure gauge.
Described cooler is dividing wall type cooler.
Described hydrogen diffuse channel connects hydrogen fuel pipeline.
A kind of bell furnace hydrogen gas recovering device of the present utility model, it is step for producing according to each table of bell furnace, what have is heating, what have is cooling, the instability of flow of useless hydrogen, is provided with recovery channel and hydrogen diffuse channel, and by solenoid control two hydrogen streams to closedown, when prevention bell-type furnace coil base igniting is produced, useless hydrogen flows into hydrogen recovery channel.Because useless hydrogen flowrate is unstable, follow-up application is exerted an adverse impact, after useless hydrogen experienced by cooling and purifying, be provided with hydrogen memory to store hydrogen, hydrogen memory is provided with Pressure gauge, to facilitate the later use of hydrogen, and when in hydrogen memory, pressure is excessive, adjustable magnetic valve one and magnetic valve two, make hydrogen be discharged, as fuel by hydrogen diffuse channel.
Accompanying drawing explanation
fig. 1a kind of bell furnace hydrogen gas recovering device structural representation of the present utility model;
In figure: 1 bell furnace; 2 hydrogen recovery channels; 3 hydrogen diffuse channels; 4 coolers; 5 hydrogen purifier; 6 hydrogen memories; 7 pressuring machines; 8 first magnetic valves; 9 second magnetic valves; 10 first Pressure gauges; 11 second Pressure gauges; 12 control valves.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, a kind of bell furnace hydrogen gas recovering device, comprises hydrogen recovery channel 2, and its inlet end connects bell furnace 1 outlet side, and outlet side connects bell furnace 1 inlet end.According to the flow direction of useless hydrogen, hydrogen recovery channel 2 is provided with cooler 4, hydrogen purifier 5, hydrogen memory 6 and pressuring machine 7 successively.Wherein cooler 4 is dividing wall type cooler, adopts the cooling of indirect water-cooling method to hydrogen.Before water receiving cooler 4, be connected with hydrogen diffuse channel 3, hydrogen diffuse channel 3 be provided with the first magnetic valve 8, the second magnetic valve 9 is installed between hydrogen diffuse channel 3 and cooler 4; Hydrogen memory 6 is provided with the first Pressure gauge 10, is provided with control valve 12 between hydrogen memory 6 and pressuring machine 7, bell furnace 1 inlet end is provided with the second Pressure gauge 11.
First magnetic valve 8 and the second magnetic valve 9 are controlled by bell furnace 1PLC switch board, when the igniting of bell furnace 1 table is produced, the first magnetic valve 8 cuts out, and the second magnetic valve 9 is open-minded, useless hydrogen enters hydrogen recovery channel 2, and successively through supercooling be stored in hydrogen memory 6 after withdrawing deposit, when bell furnace 1 needs hydrogen, open control valve, hydrogen in hydrogen memory 6 flows out, after pressuring machine pressurization, enter bell furnace 1, when amounts of hydrogen is inadequate, bell furnace 1 inlet end has other sources of hydrogen to provide hydrogen.When the first Pressure gauge 10 shows that in hydrogen memory 6, pressure is excessive, the first magnetic valve 8 is open-minded, and the second magnetic valve 9 cuts out, and hydrogen enters hydrogen diffuse channel 3, and hydrogen diffuse channel 3 connects hydrogen fuel pipeline, and this part hydrogen directly can be used as fuel.
